New Jersey Gov. Chris Christie came to Indiana Monday to address a symposium on the opioid epidemic. But at a media availability after his speech, Christie did not shy away from offering his opinion on the indictments of two former Trump campaign officials.

“It’s never a good day when these kind of things happen,” said Christie, who chairs the President's Commission on Combating Drug Addiction and the Opioid Crisis. “You never like to see that kind of conduct and activity going on.”

Christie said that he read about the charges against former Trump campaign chairman Paul Manafort and campaign associate Rick Gates on the flight from New Jersey to Indiana. He said he had not spoken with President Donald Trump Monday about this or any other topic.

Christie said he saw no indication that the charges had any connection to Trump’s presidential campaign or that any of the alleged actions had occurred during Manafort’s tenure as chair of that campaign.

But he also cautioned that at this point the charges are allegations and that both men will have their day in court.

Nor was Christie surprised that charges had been brought, he said, since FBI agents raided Manafort’s home over the summer. Christie said he would have been more surprised had no charges ensued.

Christie has had his own share of trouble. Last year two of his close allies were found guilty in so-called Bridgegate, a plot to cause traffic tie-ups on the bridge between New Jersey and New York as payback for a local mayor’s rescinding his support for Christie.
